The administration of deuterated beta-phenylethylamine to mice causes increased concentrations of deuterated para-hydroxyphenylacetic acid and meta-hydroxyphenylacetic acid within the caudate nuclei two hours after injection. Deuterated m-HPAA concentrations remain elevated at 4 hours. This suggests that high concentrations of PE
